Abstract

Die Erfindung betrifft ein Verfahren zur Ermittlung von Positionsdaten eines Messpunktes und eine Vorrichtung für das Messen der Vergrösserung in einem optischen Strahlengang. Ein Laserstrahl wird über ein Einblendelement (32a) in einen Strahlengang eines Mikroskopes eingeblendet. Ein Strahlenteiler (4c) blendet am Ende des Strahlenganges diesen Laserstrahl wieder aus und lenkt ihn auf einen Positionssensor (45a). In Abhängigkeit von der Vergrösserung der Optik (8,13) im Strahlengang trifft der Messstrahl auf unterschiedliche Positionen. Daraus kann einfach auf die definitive Vergrösserung geschlossen werden. Der Wert der Vergrösserung ist für einen Anwender wichtig, um über das betrachtete Gebiet konkrete Aussagen treffen zu können.

Figure 00000001
The invention relates to a method for determining position data of a measuring point and a device for measuring the magnification in an optical beam path. A laser beam is faded into a beam path of a microscope via a fade-in element (32a). A beam splitter (4c) blocks this laser beam again at the end of the beam path and directs it onto a position sensor (45a). Depending on the magnification of the optics (8,13) in the beam path, the measuring beam hits different positions. The definitive enlargement can easily be concluded from this. The value of the enlargement is important for a user in order to be able to make concrete statements about the area under consideration.
